oqeigure i is a front view of the registerg -with pa-rt of-the grillebroken away. r f Figure 2 is a section on line-2--2 of Figured; 1

Inthisdrawing, the lette rA indicates a portion of the walls of rooms of a building, and the letter B the floors thereof and the letter C indicates a vertical passage or conduit having openings therein opening out into the rooms so that heated air can be conveyed from a heating system or the like to the rooms. The register head or fitting is shown at D and may be provided with the double walls I to provide an'air space between the two walls I, as shown in Figure 2, or the head or fitting may be provided with but a single wall.

the upper end of the part 2 and fromthe front end of this short part 4 the said wall slopes upwardly and inwardly toward the register opening, as shown at 5, where it joins the flange 6 which fits in the register opening. This part 5 may be formed with the projections I, each of which contacts the plaster I0 of, the wall A, with said plaster engaging the flange 6, as shown in Figure 2, so that a substantially air-tight joint is formed between the plaster and the head or The rear fi t n where t ad ,o fittin P318585 through the register opening in the wall.

A dampe H is sn eegl i t e header tting nd .is hin ed pre erab y ,to th lowe .na lo the portion 2 of the rear wall of ,the heador fitting, as shown at 13. and thisd mpe ma be con.- t lled from t mom in a y 5 .119. .21 mann r, of o be n unde stood tha when h 1 d p is losed, it ext nds ae ossth :lcwermrt 0f thephead or fitt ng a d e ts on .a pa o t-the Wall 8.

The rille fp e osin the dischar eend of th head or fittlngzis shown at ,I,4, and1i,s;held1in,position in any suitable manner. j V p Thus .it wilLbe seen that the peculiar shape pf the head: or fitting proridesa .uniformd seharse of air into theroomasthe projectionsjand and the upwardly and forwardly slop n rea pa ts 3 and 5 direct the air toward the opening, and forwardly and upwardly sloping part 8 permits the air; to escaperromthelowertpart of th opening withoutbeing checked-sothat the air from the-lower part. of the openin mithmmctir cally the same velocity as it passes from the rest of the opening. When the damper H is partly closed, the device will maintain a practically equal flow of air at all points of the opening, but with a greater velocity at the bottom of the opening, where it is most desirable, especially in a head or fitting located in the baseboard or just above the baseboard. 1

With this invention, dead spots at the register opening are eliminated and there is no intake of air as in the heads or fittings as now made.

The flanges 6 and 9 act as a plaster ground as well as connecting joints between the register face and head and permits a packing of any suitable material between the register face and head so as to prevent leakage of air, which causes dirty and streaky walls.

This head or fitting may be constructed for use on any system where the flow of air is an important item and its most common use at the present time would be on hot air heating, both gravity and forced air, and indirect steam vapor or hot water systems, though its use may not necessarily be confined to heating plants .or systems.

In a fitting having an opening 8 inches high and 12 inches long and of the construction now in use, tests have proven that there is no flow of air at the bottom of the opening and for a distance of about 3 inches above the bottom. In other words, only about two-thirds of the head is efiicient and about this same ratio holds true regardless of size.

Further, the tests show the air at the bottom part of the opening is very apt to be drawn in the head or fitting, thus causing a retarding of the air being discharged and also a cooling of this discharged air because the air taken in is colder than the air discharged. 7 p

Thus it will be seen that I have provided means for diverting the air travel so as to secure a uniform flow of air through the register opening,

while preventing air from the room entering the register and retarding the flow of hot air into the room, with means for preventing leakage of air between the head and the walls of the opening, which causes disfiguration of the walls of the room.

While the device is shown and described used with an opening in a vertical wall, it is to be understood that the device can be used with openings otherwise located and it is also to be understood that the baffles formed by the parts 2, 4, 5' and! can be formedseparately or together and suitably attached to the rear wall of the head and that anynumber of these baflles may be used, as-the number used and their sizes will depend on the size of the register openings. Furthermore, the rear part of the head may be of any shape desired and the bafiie forming parts be arranged to cause the heated air to pass from the register in a uniform manner.

-It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangementof the several parts, provided that such changes fall within the scope of the appended claims.

' 'What is claimed is:

'-1.-A register device comprising a part having an opening, a conduit, and means for directing air from the conduit through the opening to provide an equal flow of air through all parts of the opening, such means comprising a head having its rear wall sloping upwardly from the rear wall of the conduit to the upper end of the opening, a front wall sloping from the front wall of the conduit to the lower end of the opening, said rear wall having a forwardly extending projection thereon, the lower end of which is substantially horizontally arranged and extends forwardly from the rear wall.

2. In a register device including a member having a discharge opening therein and a conduit, a head having a rear wall sloping upwardly and forwardly from the rear wall of the conduit to the upper end of the opening, said rear wall having an offset portion intermediate its ends forming a horizontal, forwardly extending shoulder, and said head having a frontwall sloping upwardly and I forwardly from the front wall of the conduit to the lower end of the opening.

3. In a register device including a member having a discharge opening therein and a conduit, a-

head having a rear wall sloping upwardly and forwardly from the rear wall of the conduit to theupper end of the opening, said rear wall having.

an offset portion intermediate its ends forming a; horizontal, forwardly extending shoulder, saidhead having a front wall sloping upwardly and forwardly from the front wall of the conduit tov the lower end of the opening, said rear wall, above the shoulder forming portion, having forwardly extending projections provided with horizontal tions rising therefrom thereby providing forwardly extending projections.
